Hay guys, yesterday I brought a set of irc road bike tires for my cross bike from my lbs, and last night while mounting them up, I noticed that I ended up buying one 25c tire, and one 23c tire. So I wanted to know if this would cause some sort of inbalance, and make the bike ride differently. If so do you guys think I should try to return the 25c tire and get a 23c tire in exchhange. I did not pay attention to what tires I was picking up becasue they had all the different sizes on the same hook, which they shouldn't have done. Anyways, thanks for you input.
